Just out of lingering curiousity... are you developing this app and you need help figuring out your problem? Or are you just REALLY interested as to why a page you're surfing on has an error?
Whatever the case, LWP won't help. The only way you'll get the source is to have permission, and guessing from this writeup, I don't think you do. Sorry I couldn't be of service!
If you're ever lost and need directions, ask the guy on the motorcycle.
